2025年3月20日 · Ecosystem functions are the physical, chemical, biological, and man-made processes that contribute to the self-maintenance of an ecosystem. Definition source: United Nations

2025年3月27日 · NASA’s Earth-observing satellites reveal the impacts humans have on ecosystems by collecting data on factors such as nighttime lights, forest cover, and air quality.

The Global Ecosystem Dynamics Investigation (GEDI) instrument is a full-waveform lidar installed on the International Space Station that produces detailed observations of the 3D structure of Earth’s surface. GEDI's three lasers precisely measure forest canopy height, canopy vertical structure, and surface elevation.

2025年3月25日 · Wetlands are a type of terrain where the land is permanently or seasonally saturated with water. Swamps and marshes are types of wetlands. Insects, waterfowl, fish, amphibians, and other animals often find a home in wetlands, creating a complex ecosystem that combines land-based and aquatic life.

2025年3月27日 · Having a diverse assemblage of plants, animals, and other organisms in a wide range of habitats promotes ecosystem productivity. Thriving, diverse ecosystems help balance processes like nutrient storage and recycling, pollution filtration, and water resource maintenance.

2015年12月31日 · The Millennium Ecosystem Assessment: MA Rapid Land Cover Change provides data and information on global and regional land cover change in raster format for agriculture (cropland increase and disease), deforestation (forest mask and hotspots), desertification (hotspot areas of degraded land and degradation types), and fires (most frequent and exceptional fires).

2024年7月31日 · In general, canopy structural complexity (CSC) is a measure of how leaves, branches, and stems are distributed across both horizontal and vertical spaces in a forest canopy. It also is an ecosystem attribute that can be accurately estimated from airborne- or terrestrial-lidar measurements, according to Shrestha.

2020年12月28日 · Wetlands are places where land is permanently or seasonally saturated with water, forming a distinct ecosystem that is both aquatic and land-based. Although wetlands may exist wherever water collects, they often border rivers and lakes, creating spongy coastlines astir with fish, birds, and the drone of mosquitoes and dragonflies.

2024年2月28日 · When NASA's Plankton, Aerosol, Cloud, ocean Ecosystem satellite launched into space on February 8, 2024, the team was excited for the spacecraft to begin its mission. This is not only because the endeavor was more than a decade in the making and critical for understanding Earth's ocean, atmosphere, and climate.
